New design and market research for a coffee milk forther for Quooker B.V.

Abstract

This thesis explores the design and development of an integrated milk foaming solution for Quooker’s upcoming Coffee Tap — a compact, under-counter espresso system designed to minimize kitchen clutter while delivering a premium coffee experience. While the Coffee Tap enables high-quality espresso through a capsulebased system, it lacks a milk foamer — despite the fact that nearly half of consumers regularly drink milk-based coffee. Introducing a separate device would contradict Quooker’s clean-counter philosophy, making the integration of a foamer both a strategic necessity and a design opportunity. The core challenge was to create a milk foamer that seamlessly integrates with Quooker’s hardware and interface, remains compact and easy to clean, and appeals to a broad but clearly segmented user base. To address this, the project followed a structured user-centered process based on an adapted Triple Diamond model. The methodology combined quantitative and qualitative research: segmentation surveys, emotional self-tracking, in-depth interviews, and product testing. Five user segments were defined, with special focus on Automation Seekers — users who prioritize speed, simplicity, and minimal maintenance. These insights guided the selection and development of a Venturi-based solution, using steam from the Coffee Tap’s under-counter Coffee Box to draw milk through a narrowed channel, mix it with air, and create highquality foam. The device is composed of two detachable, dishwasher-safe components, and is controlled entirely via the Coffee Tap interface, maintaining Quooker’s seamless user experience. The technical development phase involved over fifteen iterations of the Venturi mechanism, each aimed at improving foam quality, air intake, turbulence, and user handling. The final lab-tested prototype produced stable, userapproved microfoam that met both technical and user criteria. A Technology Readiness Level (TRL) assessment places the solution at TRL 5, validated in a relevant environment, indicating clear potential for future integration and upscaling. Although further development is needed to reach market readiness, including manufacturing optimization, certification, and full software integration, this thesis presents a validated and strategically aligned solution that fits within Quooker’s ecosystem and meets the needs of its future coffee users.
